| Slate is basically metamorphosed shale. Shale
is made up of slit and clay that is similar in composition to sandstone
except that the particle size is much smaller. The shale is subject to
heat and pressure and the fine particles are "melted" together to form
slate.
Slates are a natural cleft material and are typically used for flooring or roofing applications. Some slates are available in large slabs and can be used for counter tops. Most slates are suitable for exterior and interior applications. |
